The 411 on Kubernetes: Everything You Need to Know

Businesses and organizations that need portable, open-source platforms to manage their workloads in containerized forms can turn to Kubernetes. This ecosystem includes several supports and services for a variety of industries.

Kubernetes or K8s is a Greek term that translates into pilot or helmsman. With more than 15 years of history using Google tools, Kubernetes changes systems positively. Knowing how the flexible platform functions make it easier to decide how to implement it in your organization.

What are Clusters?

Kubernetes clusters run the applications within the nodes and containers. Containers give applications and their services independence to make them flexible and adaptable, so IT experts can easily develop and manage them.

The clusters become the Kubernetes management platform that gives the clusters what they need to run various machines and environments, both virtual and on-site. The clusters run on several operating systems, and they contain a master node and several worker nodes made of virtual or on-site computers.

Why use Kubernetes?

The current container applications keep services running without worry about downtime. When a container stops working, another can take care of the services to keep businesses working. Kubernetes provides resiliency, while traditional computers and storage systems do not.

Businesses that rely on Kubernetes have an easier time scaling and managing system failure than organizations without the systems. The system can recognize when a container has too much traffic and another does not, then can balance the systems to stabilize network traffic.

Kubernetes gives IT experts an automatic, in-house storage system that safely moves data to cloud providers and local storage spots. In addition, the system orchestrates storage without losing data and mishandling its movement and recall.

Another reason to use Kubernetes is the ease of rollouts and rollbacks. Stakeholders can automate the systems with new containers while removing unnecessary containers without shutting down operations.

Origins of Kubernetes

Kubernetes began as an open-source tool designed by Google. The platform gave organizations management of their microservices with a resilient infrastructure.

Businesses with Kubernetes could deploy apps and services without worrying about downtime without concerns about scaling, rollback, and self-healing as the system takes care of itself.

Now, Kubernetes can work with localized or public cloud services, including Google Cloud, AWS, and OpenStack.

Kubernetes components to know

The platform has a unique set of terms that can be confusing for people who aren’t familiar with it. If you begin using Kubernetes, you’ll need package management and a container storage interface (CSI) that gives you room to package, store, and deploy services. Kubernetes also has a container networking interface as a framework to configure resources dynamically.

When Kubernetes experts talk about services, they refer to the catalog of applications available within the system. Fortunately, Kubernetes includes exceptional security options that meet the needs of all types of businesses.

How Kubernetes looks in a business

The foundation of Kubernetes is the control plane that manages the controlling node and contact point. The server has several unique components like the Kube-API server, cloud-control-manager, and Kube-scheduler.

On the client side, Kubernetes has machines that run the containers and cluster nodes like the kubelet and Kube-proxy.

The users access Kubernetes through a dashboard with a universal design that lets them learn about the workloads and clusters. The dashboard gives stakeholders control of the workloads and provides detailed reports regarding activity logs and resource records in the nodes.

Wrap up

The learning curve is steep with Kubernetes, but after building a better understanding, you’ll have an easier time managing your company’s systems and preventing downtime. Having Google at the heart of the system gives users immense capabilities that other platforms do not offer.
